GASKET-MAKING MACHINE.

Application filed March 13, 1916.

T 0 all 'whom t may concern:

Be it known that l, IRA A. POWELL, a citizen of the United States, and aresident of St. Louis, in the State of Missouri, have invented a certainnew and useful Improvement in Grasket-h/laking` Machines, of which thefollowing is a specification.

One of the principal objects of my invention is to provide an improvedmachine for making gaskets or washers, incorporating means for shapingthe gaskets, stamping or compressing the same, and then re moving themfrom the die.

Another object of the invention is to provide a gasket making machinewhich will be extremely simple, durable, eflicient in operation, andinexpensive to manufacture.

With these and other objects in view which will become apparent as thedescription proceeds, the invention resides in the construction1combination, and arrangement of parts hereinafter more fully describedand claimed, and illustrated in the accompanying drawings in which likecharacters of reference indicate like parts throughout the severalfigures, of which- Figure 1 represents a view in front elevation of agasket machine constructed according to my invention. Fig. 2 representsa side elevational view thereof. Fig. 3 reprcsents'a view in sectiontaken horizontally on the plane indicated by the line 3-3 of Fig. 1.Fig. 4 represents a fragmentary view partially in section, showing theposition of the parts after the gasket has been shaped on the die. Fig.5 represents a view similar to Fig. 4, showing the position of the partsat the completion of the compressing operation.

Referring more particularly to the drawings, the machine includes a pairof spaced vertically extending parallel standards 5, which may be formedof lengths of I-beam, the standards being secured by means of angles 6to the gtioor of the shop, and at their upper ends being connectedtogether by means of plates 7. Secured by means of angle irons orbrackets 8 to the uprights 5, is a horizontally arranged table or plate9. lt is partly supported by means of the legs 10 secured at their upperends to the table, and at their lower ends bolted or otherwise fastenedto the Hoor. The table is provided with an opening 11, through which adie 12 carried on the upper end of a vertical shaft 13 is adapted topass. This shaft 13'is'slidably and rotatably journaled Specification ofLetters Patent.

in abearing 14 carried by the uprights 5 beneath table 10, and the shafthas a bevel gear 15 slidably keyed thereon, said gear being supportedupon a cross piece 16 carried by the legs 10: A bearing 17 secured tothe' cross piece, slidably receives the shaft 13. A, spring 18interposed between the lower end of the shaft and the floor normallymaintains the shaft at the upper end of its path of movement, so thatthe guide 12 will be positioned vabove the table 10.

A horizontally arranged main shaft 19 is journaled in bearings 20,between the uprights 5 near their upper ends, and is adapted to becoupled by means of a clutch 21 with a pulley 22 driven by means of abelt 23 from a suitable source of power. A pulley 24 operated from thepulley 22 drives belt 25, which in turn drives a pulley 26 carried on ashaft 27 which is journaled adjacent the lower `ends of the standards 5in bearings 28. This shaft 27 carries a pinion 29 which meshes with thepinion 15, whereby the die 12 may be driven in a rotary manner. f

A crank arm 30 carried on the shaft 19 is connected by an adjustable rod31, with a pin 32 carried byv a vertically arranged squared rod 33 whichis guided for reciprocationin bearings 34 carried by the uprights 5. Theadjustable rod 31 comprises segments connected by a turnbuckle 35 whichmay be operated `for drawing the seg ments toward each other, or forshifting` them apart. ln this manner, the path through which the pilot36 carried at the lower end of rod 33 reciprocates, may be varied. Thepilot 3G is circular, being arranged above the die v12, and is taperedat its lower end as at 3 7. A circular flange 38 is carried near theupper end of the pilot.

A stripper 39 in the nature of a plate having an opening therein throughwhich the pilot 36 may project, and having upstanding arms 40 at itsrear portion, which arms lie against the uprights 5, is provided. Thearms 40 of the stripper have slots 41 cut therein, and bolts 42 carriedone by each of the uprights 5 project through these slots and guide thestripper in its up and down movements. A lever 43 having a bifurcatedinner end between the prongs of which a corrugated roller 44 isjournaled, is pivoted as at 45 to the table or plate 9. The lever 43 maybe moved in one direction or the other, for bringing said rollery 44toward or away from the die 12. This die is circumpath of movement, forstripping the gasket from the pilot.

3. A gasket making machine, including a table, a die arranged above thetable and adapted to be vertically reciprocated through an openingprovided in the table, said opening being of a diameter substantiallyequal to the diameter of the die, means for compressing an unfinishedgasket against the die whereby to impart the configuration of the die tothe gasket, a pilot arranged above the die, said pilot being of adiameter substantially equal to the diameter of the die, means wherebythe pilot may be vertically reciprocated for moving the die through theopening in the plate, resilient means for returning the die to itsnormal position, a stripper arranged between the die and pilot andhaving an opening through which the pilot is projected when moveddownwardly, said pilot being provided with a flange for engaging thestripper whereby to move the latter downwardly with the pilot, and meansfor limiting the upward movement of the stripper prior to the arrival ofthe pilot at the upper end of its path of movement, whereby to strip thegasket from the pilot.

4. A gasket making machine including a table having an opening therein,a circumferentially corrugated cylindrical die arranged above the platein alinement with the opening and adapted to be shifted downwardlythrough said opening, means for re turning the die to its normalposition, means for rotating said die, a circumferentially corrugatedvertically arranged roller adapted to be moved toward and away from thedie for imparting the configuration of the die to an unfinished gasketarranged on the die, a pilot arranged above the die, means forreciprocating the pilot in a vertical path at will, for driving the diethrough the opening in the plate whereby to Compress the unfinishedgasket against said plate, said pilot at its lowerpend being of adiameter substantially coincident with the diameter of the die wherebythe pilot may advance through the gasket for imparting the properinternal diameter thereto, and means for stripping the gasket from thepilot as the latter moves upwardly.
